Method: This prospective randomized single center trial was conducted on three groups of patients under going CABG. The study was conducted from 1st January 1999 to December 2002.The first group A (n=15 with mean age of 47.05±8.35years) Radial artery was used for grafting in Right and Left sided grafts except the LAD. In the second group B (n=15 with a mean age of 54.80±11.14 years) Great Saphenous Vein was used for grafting in Right and Left sided grafts except the LAD. In the third group C (n=20 with a mean age of 55.93± 11.14 years) IMA was only grafted to LAD. Proximal ends of both the GSV and the Radial Artery were anastomosed to the Aorta. All patients were male . Follow up was done in these patien ts both by non invasive and invasive methods such as ETT , Thallium scan , Angiography. Comparison was mainly done between the Radial artery and the Great Saphenous Vein taking as granted that the IMA g the best graft for the LAD in all cases. Results: IMA was always applied to LAD in all patients in the three groups. In group (A) Radial Artery was grafted to RCA in 5 (33.3%) pts. Diagonal in 4 (26.7%)pts. Obtuse Marginal 12(80%) pts. And PDA 3 (20%) pts. In group (B) Great Saphenous Vein was grafted to RCA in 6(40%)pts. Circumflex 1(6.7%)pts. Diagonals 2 (13.3%) pts. Obtuse marginals 6 (40%) pts. And on PDA 4(20%) pts. All patients were regularly followed up for 18 months to 24 months. Post operative angina was reported in 2 (13.3%)pts. in group A and 5(33.3%) pts. In group B (p=0549). ETT was done in all these pts. Was positive in 1(6.7%) in group A and 2 (13.3%) in group B (p=0.309). Thallium scan was done in all the study population and was found positive in 4 (26.7%) in group A and 5 (33.3%) in group B Patients(p=0.265). Coronary angiograms were done on 10 patients out of each group. In group A the grafts were patent in 9 patients (90%). In the group B the grafts were found patent in 8 (86%) patients.(p=0.543). Moderate Graft stenosis was found in 01 patient in group B and none in group A (p=0.35). Totally blocked grafts were found in 01 patients in each group (p=1.00).</p> ER -
